First, it detects if the image is a "pure" ME image (magic $FPT at offset 0x10) or a full BIOS dump (magic 5a a5 f0 0f at offset 0x10). If it is a "pure" ME image it uses the whole file as
ME image, otherwise it finds the ME region by reading the values inside
the Intel Flash Descriptor. Then it searches for the basic ME informations: presence of the FPT
region, version of the firmware, number of partitions and offset and
size of the FTPR partition.
